You still aren't even reading. I think it's obvious why. I'm guessing some of you haven't read about Bungie's time at Microsoft. I suggest you google it for research. I think the writing is on the wall and Bungie has been vocal about their displeasure of working for Microsoft.

Then post a link before you start making claims its that simple.

Actually...that does make them hypocrites. Doing something and expecting the competition not to be able to do the same thing is hypocrisy. Microsoft better get all of the multiplat titles on time with no timed exclusivity on other consoles because Xbox gamers will suffer from Microsofts intolerance of the very rules they break with timed exclusivity themselves. They just wont accept games if they come late to their console. They can do it but no one else can. At least Sony doesnt bitch like them.

Does not matter to me Destiny looks 100x better than Halo.

apparently Bungie saw that all they would do with MS was Halo, so they went independent, and now they call the shots. and as i've heard, they own the rights to Destiny

half of the staff joined MS after they split up?!
You don't join the company that treats you that bad.

If they treat bungie like crap bungie should become another IW and there will be no 343i and Destiny will develop by a new studio with fromer Bungie staff.
But they don't,they let them go

No point reasoning in a thread like this

True. BTW Bungie always stated MS treated them well, particularly about the conditions that set them free. But obviously they wanted to explore new ideas too, they have a talent way above average and they proved many times they can use it in many different franchises and genres. We can see how immense they are comparing Myth I and II, made by them, with Myth III, made by others and utter crap.
So yes, there are mostly reasons on both sides and I'd say very few wrongs on both sides too. Their roads simply split.
MS has behaved far worse in its history, even with its own employees, when that greedy lard ball cut benefits to some of the most productive employees in the world to gather another billion, but surely not towards Bungie, and about being bastards with the devs I think nobody can beat Activision and that Skrotick thug.
